I think the issue is, dudewhoneverleavesbasement.com stopped working on his website and his potential successor is more likely to be trying to turn that information into an interesting youtube video.
I think this is definitely an issue but not the only one. In the game knowledge part of the web, there used to be personal sites written in plain html of some guy’s faq who figured out every single thing in a final fantasy game and google would draw on stuff like that. Now you get AI SEO spam heavily monetized drivel that contains a lot of inaccurate or outright false info.
I think the small sites like that are either mostly gone or simply not ever indexed.
